A spring; 255 is provided to uolguoto tho rorl 21 when the ltU catch 23 is released from engagement with the trigger 24 by the action of the magnet 27 upon the armature 26, as hereinafter described. A spring 29 is provided to insure the engagement of the trigger with the catch when the rod 21 is pulled to the right to start the machine. The connections from the hattery 30 to the magnet 27 by the wire 31, and through the wire 32 to the spring contact 33, willbe apparent, and the circuit is completed through the wire 34 and connection 35 to the carrying arm 36 and the sound box arm. .V hen the phonograph is under way, the parts of my device are in the position shown in Figure 1 and the current is conducted from the spring 33 through the arm and the frame 43 to the wire 37, secured to the plate 15, and from the plate to the driving shaft 16, (Figure 2), which drives the disk platel73 and through it, rotates the record disk 78. From the shaft 16, the cir cuit passes to the plate 38 secured to the disk,- by the contact with the driving shaft of the sensitive spring 3?). The other end of the circuit, through the carrying arm 36, and the sound box arm, is conveyed to the spring finger -10 which is att: ched to the sound box 78 by suitable means, such as shown in Figure 8. The spring linger l0 is allowed rotary movement on its shaft 41 in order to protect the stylus from any sudden jar caused by the contact of the terminals 38 and 40, but a sonlever 21 (pivotedat 20) is moved to sitivespring 42 is provided to maintain the spring finger 4-0 normally in 'a vertical position. In the side of the frame 43 (see Figure 5) which carries mycutoff device, is provided a slot 44 which accommodates the end of the arm. 23 and by means of this slot the rod 21 is allowed rotation of about forty five degrees, but the coil spring 28 acts to normally prevent such-rotation.

As shown in Figure 6, the spring 39 of plate 38 is provided with a pin 67 to engage the mortise 68 in the driving, shaft 16, (Figure 7) if desired, and the plate 38 is preferably provided with an inclined front edge 74.

in order to make contact gradually with the spring finger 40.

Referring now to Figures 10, 11, and 12, showing the application to a cyliud r phonograph, it will he .centhat the battery circuit is made through the wire 45 and coil 27, insu- 'lated from plate 15, and the wire 46, through the connection 47 (which is fastened to the plate 15 but insulated therefrom) to the standard 49, also secured to but insulated from. the plate The other end of the cir cuit through the wire 51, is conducted to the hanger 52, an contact screw .55, carried on but insulated lrom the plate 15.

This s ring makes circuit through plate 15 and t e mandrel 59, carried in'the usual manner in bearings supported on the plate, and thence by the spring (see Figure 12) to the metal insert 61 provided in the cylinder record 76. The two terminals are thus thestandard 49 and the insert 61. A suitable rider such as the spring 62, is attached to the sound box holder 71 to engage with the standard 49, when the reproducer has trav- 5 ersed the greater part of the record. This rider is made of any flexible conducting material, and is insulated from the holder 71 (Figure 12) but is in contact with the wire fi l which connects with the insulated spring finger 79. A spring 66 is arranged in any suitable manner to protect the stylus 82 from thedanger of striking the insert 61. The current is thus passed to the spring Fmger 79 and the circuit will be completed when 85 it engages the insert 61. 1

In Figures 8 and 9 (and in dotted lines in Figure 2) l have shown a modification wherein one terminal of the circuit is the sliding, finger 38 which is secured adjustably on the arm 69, which 'is carried by the arse 13, so that the circuit is made from We magnet through the wire 37, directly to the arm'at 81 as outlined in Figure 2.

' In. Figure 10 lhave shown another modii'i- 9 5 cation in which a rod 72 having a keyed sleeve 50 slida oly mounted thereon, carries a screw 50 to engage the holder 71 i A guide 50 for the accurate adjustment of the screw 5O with reference to the sound groove is also provided on the sleeve 50.

The operation of my device on a disk machine with the motor rotating disk 73, is as follows: The stylus 74 moving in the sound groove, will carry the spring linger 40 toward :0 5 the center till it makes contact with the plate The inclined edge '74 of the plate 38 provides a gradual connection with the finger 40, in order to prevent injury to the sound box or the stylus. If a good connection is not 11c secured on the first contact, it will be secured on another revolution of the disk when the stylus will have moved perceptihly toward the center and the spring finger will then engage the slant of the plate at 'M and be rotated upward and coi'isequently inward toward the center of the disk, thus making a perfect connection, without conveying any motion to the stylus. By abruptly covering the unused portion of the record by widely 12o separated sound grooves, tne contact of the terminals could be facilitated, aswill be obvious. Immediately upon the circuit being closed, the magnet 27 will operate upon the,

armature 26 and the trigger 24 will release 12 5 the catch 23, and the spriir will actuate the rod 21, which, by its connections as described, will move the brake shoe 19 against the disk 18 and thereby arrest the motor.

The sleeve 50 can be moved longitudinally on the rod 72, (which can be extended the entire length of the record if tiesired), and by moons of the guide 50*, the rotation of the record may be stopped at any predetermined point.
